The answer is A
Explanation-
3x + 4= 2x + 6
-4 = -4
3x=2x + 4
-2x= -2x
X=4
<h2>Answer</h2>
0.43
<h2>Explanation</h2>
Remember that
Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so . Now, the sum of all frequencies will be the sum of all the 10th graders, so . Let's replace the values:
And rounded to the nearest hundredth:
<h3>
Answer: Choice A) 3/40</h3>
Check out the diagram below. I have labeled the marbles 1 through 20 to help count out them easily.
We have 3 blue marbles out of 20 total. The probability of selecting blue is 3/20.
If we put the first selection back, then we will still have 20 marbles overall. The are 10 green marbles out of 20 so the probability of getting green is 10/20 = 1/2
Multiply the probabilities 3/20 and 1/2 to get (3/20)*(1/2) = (3*1)/(20*2) = 3/40
Answer:
3 19/24

<h2>
Hello!</h2>
The answer is: 4.0 (at Richter scale)
<h2>Why?</h2>
The answer is 4.0 Assuming the standard earthquake as 1.0 (at Richter scale).
An earthquake of 1.0 at Richter scale is equal to:
An earquake of 2.0 at Richter scale is equal to:
and so...
Therefore,
An earthquake of 4.0 at the Richter scale is equal to:
So, it means that an earthquake with 4.0 magnitude at the Richter scale is 10000 times more intense than a standard earthquake, assuming it as 1.0 at Richter scale magnitude.
Have a nice day!
